Before you venture out on this year’s Christmas Bird Count, please review these frequently confused birds.

Know Your Christmas Bird Count Birds – A few species confusions to watch

It is important, and often very helpful for ID, to be aware of the bird species that you are likely to find during the Christmas Bird Count season in Colorado. Many species that you would find in high numbers in the summer are, at best, extremely rare in the winter. While you should not completely disregard the possibility of these rare winter species being present, you are generally safe ignoring them. Below, pairs or trios of birds are briefly described to highlight differences. Please make a point to familiarize yourself with these and the temporal ranges of other common Front Range species. Have a great CBC season!
